Our Turtle Tough CW-II Immersion pH Sensor contains utilises our most affordable and budget conscious CPVC body material. A key feature of this sensor is a compact style solid-state, non-porous, cross-linked polymer embedded in a HDPE support matrix. This enables the sensor to hold excess KCl assuring saturation at all temperatures for stability and long sensor service life in applications where little or no maintenance will be performed. The standard glass is many times stronger than common pH sensors and delivers an outstanding broad range performance. The CPVC immersion style body has a ¾” MNPT threaded connection on the front and back end. Recommended applications include industrial, chemical, food & beverage, semiconductor, pharmaceutical & wastewater. Any measurement where aggressive chemical cleaning is needed to remove fouling or low-maintenance operation is required with minimal cleaning and re-calibration.
